How we should Attack.—The reasons for which men believe or do not believe are in very few people as strong as they might be. As a rule, in order to shake a belief it is far from necessary to use the heaviest weapon of attack. Many attain their object by merely making the attack with some noise—in fact, pop-guns are often enough. In dealing with very vain persons, the semblance of a strong attack is enough. They think they are being taken quite seriously, and readily give way.
